i like the concept! its interesting and fun thats for sure. i liked the sound effects and the menu especially. it was nice that there was settings too! many games didnt have those.
onto feedback, i think that the tutorial being embedded into the game itself would've helped a lot. its better you had a tutorial in the first place as many didnt have them that i have played sofar but unfortunately the tutorial just felt sort of like word vomit and i couldn't properly process it. this also lead to me being confused in the game itself for a bit, i played around and eventually understood the mechanic but it was difficult for me.
the game itself felt a bit too hard, i think the concept was fun and intuitive but there should've been more room to move the blocks or just more time. it felt very pressuring that i only had 2 minutes and i just couldnt figure out how to make the right line for the creatures. it oftentimes lead to a bit of annoyance because of how it just didnt seem i could get it to work.
all that being said i think that with improvement this could be a solid game! as a fan of the puzzle genre i did enjoy it to some degree.
